KBU407G T0G

Overview

The KBU407G T0G is a glass passivated bridge rectifier manufactured by Taiwan Semiconductor. It provides a maximum repetitive peak reverse voltage of 1000 V and a maximum average forward rectified current of 4 A. The device features a typical instantaneous forward voltage of 1.1 V at 4 A and a maximum DC reverse current of 500 μA at 125°C. It supports a peak forward surge current of 150 A for an 8.3 ms half-sine wave. Operating junction and storage temperatures range from -55°C to +150°C. The component utilizes a KBU case with matte tin-plated leads, weighs approximately 7.2 g, and meets UL flammability classification 94V-0.

Feature Summary

Glass passivated junction construction for enhanced reliability
Halogen-free green molding compound compliant with IEC 61249-2-21
High case dielectric strength suitable for printed circuit board mounting
Matte tin plated leads solderable per JESD22-B102 standard

Applications

General purpose AC to DC power supply rectification
Industrial equipment power conversion circuits
Consumer electronics power adapters

Procurement Notes

Verify the specific ordering suffix T0G against official Taiwan Semiconductor documentation to confirm packing code details. Ensure compliance requirements such as RoHS Directive 2011/65/EU are explicitly validated for the intended application environment before finalizing procurement specifications.

Selection Notes

Select this component when a 1000 V reverse blocking capability and 4 A continuous current rating are required in a compact KBU package. Consider the thermal resistance values and derating curves if operating near the maximum temperature limits or under high surge conditions.

Part Context

This part belongs to the KBU40xG series of glass passivated bridge rectifiers from Taiwan Semiconductor. The series covers voltage ratings from 50 V to 1000 V, sharing identical mechanical dimensions and electrical characteristics except for the reverse voltage parameters. The 'G' suffix indicates the use of halogen-free green compound.
